Filter by:Cow's milk allergy (CMA) is the most common Food Allergy (FA) in children, and the essential strategy in prevention is avoiding the allergens that may cause potentially life-threatening reactions. The primary developmental task of early childhood is the creation of healthy eating habits. The diagnosis of FA in this period can lead to permanent changes in the life of the child and her family. In early childhood, parents are often responsible for all aspects of FA management because children are too young to understand the complexity of avoiding allergens. Children often do not have the skills to implement FA management. Parents are advised to follow a special weaning diet, avoiding any type of cow's milk, usually at least 1 year old. However, depending on the clinical improvement, it can be recommended to continue this exclusion diet for much longer. Thus, many children have to exclude a large group of food from their diets, which is critical for their growth, development, and eating habits. This may raise mealtime behavioral anxiety in a child with a FA. Eating behavioral anxieties are also very common in healthy, typically developing children. Even 25% to 45% of normally developing children's parents report concerns about their child's nutritional and mealtime behaviors, including the destructive child behaviors (eg., refusal of foods, food selectivity, and getting off the table). In children with food allergies, monitoring long-term growth after the diet is another important issue. Growth problems were reported in 21% of children with FA diagnosed with malnutrition. Most studies focused on the effect of changes in eating behavior on growth during an elimination diet or in short term intervals. Its long-term effects have only been analyzed in a few studies. We aimed to investigate the eating behaviors, nutritional status, and growth of young children (ages of 2 to 6) who had a strict diet due to CMA in early childhood (ages of 0-2).
This study evaluate the mineral status of infants with cow's milk protein allergy which is affected due to the elimination of milk , and the change in this mineral status after receiving amino acid - based formula for 12 weeks.
In this study, fecal and urine samples will be collected from children diagnosed with : - IgE mediated cow's milk allergy, - suspected of a cow's milk allergy, but with negative diagnosis - IgE mediated food allergy other than cow's milk - healthy brothers and sisters of the first three groups A subset of patients with IgE-mediated cow's milk allergy will be asked to provide a urine and fecal sample yearly for prognostic purposes. The samples will be analyzed using a technique called metabolomics to identify biomarker candidates with diagnostic and/or prognostic potential. Additionally, microbiome analysis will be performed to map the microbiome of all groups.
Lactobacillus GG (LGG) is able to exert long lasting effects in children with atopic disorders. Nutramigen LGG accelerates tolerance acquisition in infants with cow's milk allergy. The mechanisms of these effects are still largely undefined. The effect of LGG could be related at least in part by the immunoregulatory role played by LGG. This probiotic can balance the generation of cytokines possibly involved in IgE- or non-IgE-mediated cow's milk allergy Interleulkin (IL)-4, IL-5, IL-10, IFN-γ , TGF-β, and TNF-Υ), which can contribute to modulation of inflammatory processes. The investigators have demonstrated that children with IgE-mediated CMA produce significantly higher level of IL-4 and IL-13 in response to cow's milk protein, and that tolerance is associated with a marked reduction of IL-13 production and a concomitant increased frequency of IFN-γ releasing cells. Epigenetics studies the heritable (and potentially reversible) changes of the genome inherited from one cell generation to the next which alter gene expression but do not involve changes in primary DNA sequences, highlighting the complexity of the inter-relationship between genetics and nutrition. There are three distinct, but closely interacting, epigenetic mechanisms (histone acetylation, DNA methylation, and non-coding microRNAs) that are responsible for modifying the expression of critical genes associated with physiologic and pathologic processes. The profile of epigenetic modifications associated with Th lineage commitment, coupled with the sensitivity of the early developmental period, has led to speculation that factors that disrupt these pathways may increase the risk of allergic diseases. Specifically, effects on DNA methylation and endogenous histone deacetylase inhibitors acting on specific pathways (Th1 and T regulatory cell differentiation) may favour Th2-associated allergic differentiation. MicroRNAs are another structural components of an epigenetic mechanism of post-transcriptional regulation of messenger RNA translation. It has been recently identified a specific Th2-associated microRNA (miR-21) that is critical for the regulation of Th cell polarization. It has been previously demonstrated an inverse DNA methylation pattern of cytokines involved in Th2 response (IL-4, IL-5) compared with cytokines involved in Th1 response (IL-10, INF- y) in children with CMA acquiring oral tolerance, with the most pronounced effects in those treated with Nutramigen LGG.
This study of the tolerance and acceptability of a extensively hydrolysed formula (eHF) containing pre- and probiotics will assess gastrointestinal (GI) tolerance, product intake and acceptability in 40 infants (aged <13 months) currently using or requiring an extensively hydrolysed formula for the dietary management of CMA. Patients already prescribed an eHF (or other appropriate feed for CMA) at time of recruitment will undertake a 3 day baseline period in which their current symptoms, compliance, GI tolerance and acceptability towards their current feed is assessed, before introducing the study product for a period of 4 weeks. Patients who are not on an eHF (or other appropriate feed for CMA) at baseline will forgo this 3 day baseline period and immediately introduce the study product for 4 weeks.
COMISS score for detection of Cow's Milk Protein Allergy in children with recurrent or persistent gastrointestinal manifistations in infants attending Assuit University Children Hospital
The main aim of this study is to provide longitudinal growth data in infants with moderate-to-severe cow's milk allergy fed an amino acid-based formula with two added human milk oligosaccharides.
This study will assess a novel and potentially life-changing therapy, by actively treating Cow's Milk Allergy (CMA) using Oral Immunotherapy, which may allow patients to safely consume milk and other dairy products.
The aim of this study is to show the hypoallergenicity of a new thickened rice based formula (TRHF) through a double blind placebo controlled food challenge (DBPCFC), as recommended by the American Academy of Pediatrics, in subjects with IgE-mediated CMA and in subjects with non-IgE-mediated CMA.
The study will assess the diagnosis of Cow's milk protein allergy (CMPA) among infant and children in Assiut University Children Hospital using skin prick test and specific serum IgE
